About this study

Official title: Short-Term Clinical Outcome Including Dislocation Rate and Ceramic Fracture of Total Hip Arthroplasty Using Larger Diameter of 4th Generation Ceramic Bearing

The primary objectives of this clinical study include:

  • Assess the rate of dislocation and fracture of THA using the new (the 4th generation) ceramic implants.
  • Evaluate the survival rate of THA using the new alumina-zirconia (the 4th generation) composite ceramic bearing.
  • Investigate the performance of the 4th generation ceramic implants mostly in patients younger than 50 years.
  • Compare the preoperative and postoperative scores of Harris Hip Score, UCLA Activity Score and WOMAC.
Read the detailed description

This study will evaluate incidence of dislocation and short-term clinical outcome on patients who undergo large diameter 4th generation ceramic bearing total hip Arthroplasty ("THA") in comparison to historical data on 3rd generation CoC THA (28mm) patients. Specifically the study intends to address the following research topics:

  1. The incidence of dislocation after THA with use of the 4th generation Ceramic Bearing in comparison to 3rd generation Ceramic Bearing.
  2. The incidence of ceramic fracture after THA with use of the 4th generation Ceramic Bearing in comparison to 3rd generation Ceramic Bearing
  3. The survival rate, wear rate, and incidence of osteolysis of THA with use of the 4th generation Ceramic Bearing
  4. Range of motion improvement from preoperative to postoperative to support Korean sitting style after THA with use of the 4th generation Ceramic Bearing.
  5. Clinical outcomes, activity level and QoL of patients with use of the 4th generation Ceramic Bearing.
  6. The performance of THA with use of the new ceramic bearing mostly in patients younger than 50 years.

Questions about this trial

What is this clinical trial studying?

An observational study of Arthropathy of Hip, run by Zimmer Biomet at 4 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Dislocation (time frame: 12 month postop). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2018.
